The Wacker Neuson is a genuine OEM Lock Washer designed for the PT6 series self-priming centrifugal trash pumps, including PT6LT, PT6LS, PT6Y, PT6YT, and PTK6 models. As a factory-sourced component, it meets the original engineering specifications and installs directly without modification. This Lock Washer is verified against multiple PT6 configurations spanning standard, skid-mounted, trailer-mounted, and Tier 4 compliant variants, giving you confidence that is the correct part for your machine. Keep a spare on hand — hardware like this is easy to overlook during maintenance but critical when it's missing.
Key Features
- Genuine OEM Hardware Grade — Sourced directly from Wacker Neuson, this Lock Washer is manufactured to the exact hardness and dimensional tolerances specified for PT6 pump assemblies, ensuring proper clamping load and thread retention.
- Drop-In Installation — Matches the original fastener stack-up on PT6 series pumps, seating correctly against mating hardware with no rework or sizing adjustments needed.
- Broad PT6 Series Coverage — Confirmed fitment across PT6LT, PT6LS, PT6Y, PT6YT, and PTK6 variants, including Tier 4, skid-mounted, and trailer-mounted configurations.
- Fastener Integrity Under Load — A correctly functioning lock washer prevents fastener loosening caused by pump vibration during operation; a missing or worn one can allow critical hardware to back out over time.
- Verified by Part Number — Part number 5000072861 is cross-referenced against multiple PT6 model and machine numbers, so you can order with confidence that this is the right washer for your pump.
A lock washer is a small but essential piece of hardware that sits beneath a bolt or nut to resist loosening caused by vibration and dynamic loads. In a high-cycle application like a trash pump — where the engine and impeller generate continuous vibration — fasteners without proper locking hardware can gradually back out, leading to component misalignment, fluid leaks, or structural failure. Replacing a worn, distorted, or missing lock washer with a correct OEM-spec part like the Wacker Neuson 5000072861 restores proper clamping force and protects the integrity of the fastened joint throughout the pump's service life.
